CUSHION-TREAD HORSESHOE.

Application filed February 15, 1813.

To all whom it may concern Be it known that we, ROBERT E. FRUIN and THOMAS TOBIN, both citizens of the United States, and residents of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Tmprovements in Cushion Tread Horseshoes, of which the following is a specification.

This invention relates to improvements in horse shoes of the cushion-tread type, and has reference more Jarticularly to improvements in that specific form of cushion-tread horse shoes that is characterized by the pro vision of an integral connecting bar between the heel cushion pads, for supporting the entire heel portion of the hoof of the animal.

Among the leading objects of the invention are to provide a construction designed to afford a more ample and substantial support to the heel than has heretofore been attained in shoes of this character; to pro vide a construction affording greater durability and longevity to the heel cushion; to provide a construction embodying a toe cushion well adapted for cooperation with the heel cushion; to provide a construction that shall afford a secure footing upon the surface of the roadway and shall not become slippery with wear; to provide a construction affording a maximum cushioning efiect while at the same time allowing ample nailing space for attachment of the shoe to the hoof; and, generally, to improve, in respect to comfort, durability and efficiency, cushiontread shoes of this general type.

Our invention, its novel structural features, and the merits and advantages secured thereby will all be readily understood when considered in connection with the accompanying drawing, in which- V Figure 1 is a bottom perspective view of the metal frame of our improved horse shoe. Fig. 2 is a similar view of thecomplete shoe; and Figs. 3 and 4: are sectional details on the lines 33 and M, respectively, of Fig. 2.

Referring to the drawings, 5 designates as an entirety the metal base plate of the shoe frame, on the under or tread surface of which are formed a hollow toe calk comprising an outer wall 6, an inner wall 7 side walls 8, and a pair of hollow heel calks comprising outer and inner side walls 9 and 10, respectively, and inner end walls 11. The base plate 5 is formed with inwardly curved heel portions 12 that are gradually widened toward their inner rear ends, as clearly Specification of Letters latentf Patented May a, 1915.

shown in Fig. 1, and are formed with rounded edges 13 at their inner rear ends; said inwardly curved heel portions of the base plate forming the bottom walls of the hollow heel calks, and provided with apertures 14 for a purpose hereinafter disclosed.

The outer and inner side walls 9 and 10 of the heel calks are separated by a space approximately equal to the width of the inner rear ends of the curved heel portions 12, forming openings to accommodate the connecting bar of the heel cushion, as more particularly hereinafter described.

In the hollow toe calk is a toe cushion 15 that completely fills said toe calk and overlaps the edges of the outer, inner and side walls, thereof, as clearly shown in Figs. 2

and 3. In the heel calks are similar cushion pads 16 that are of somewhat greater thickness than the depth of the heel calks and overlap the edges of the outer and inner side walls 9 and 10, as clearly shown in Fig. 2; and integral with said heel pads 16, and connecting the same through the open sides of the heel calgs, is a connecting bar 17, the tread surface and sides of which are made flush with the tread surface and sides of the pads 16.

In the manufacture of the shoe, the toe and heel cushions are made of rubber, and the uncured rubber, having been forcibly packed and shaped in the calks of the shoeframe, is then vulcanized in place; and by permitting the rubber to overflow or overlap the edges of the containing walls, an ample and secure support for the pads is afforded, preventing tendency of the pads to rock and work loose in their seats in the calks. The integral connecting bar 17, aside from furnishing a desirable transverse support to the heel of the animals hoof, contributes largely to the rigidity and stability of the heel pads 16 under the wear and tear of service. When the uncured rubber is'forced into the heel calks under the pressure of a suitable die,

a portion of this rubber is squeezed through.

the apertures let to the upper side of the base plate; and over the latter, to approximately the surface extent of the entire heel cushion, is applied a canvas or similar fabric 18 that adheres to the surface of the base plate through a thin skin of rubber indicated at 19 in Fig. 4. This fabric and rubber skin not only protects the heel of the animal from contact with the metal of the shoe frame, but it also forms an anchorage for the heel pads calk, a pair ofihollow heel calks, each hav-.

16, the latter being keyed thereto by the in} tegral parts thereof forced through the edges of their containing calks, said inter-' mediate calks 2O afford an additional or auxiliary grip or hold on the surface of the road to prevent slipping. Furthermore, the intermediate calks 20, springing as they do from the inner edge of the base plate, allow ample room on their outer sides for nailing through the nail holes indicated at 21;

' We claim o 1. A cushion-tread horseshoe, comprlslng a base-plate having inwardly curved heel portions of increasing width toward their rear edges and rounded at the latter, a toe ing an inner end wall, an outer side wall extendingalong the outer edge of the heel portion :to and slightly beyond the outer side of said rounded rear end, and an inner side wall approximately half the length of J the outer side wall extending from said end wall along theinner edge of the heel portion to the inner side of'said rounded rear end, intermediate calks between and continuous with the inner walls of said toe and heel.

calks, said intermediate calks and inner walls of. the toe and heel calks springing from the inner edge of the base-plate and having their inner sides flared outwardly from the hoof to the tread side of the shoe, and a heel cushion comprising cushion pads filling said heel calks and a cross-bar integral and flush with said cushion pads and connecting the latter through the spaces be tween the rear ends of said sidewalls.

2. A cushion-tread horseshoe, comprising a base-plate having inwardly curved and apertured heel portions, a pair, of hollow heel calks each having an outer and inner side wall and an inner end wall and open on their adjacent sides across the inner rear ends of said heel portions of the base-plate, a heel cushion comprising cushion pads fill- Gopies of this patent may be obtained for ing said heel calks and extending through the apertures in the bottoms thereof and a cross-bar integral and flush with said cushion pads and connecting the latter through the open adjacent sides of said heel calks, and a fabric covering onthe hoof side of the rear portion of said base-plate substantlally coextensive with said heel cushion.

3. A cushion-tread horse-shoe, comprising a base-plate having a pair of hollow heelcalk-s open on their inner opposed sides, a heel cushion comprising cushion pads filling said heel-calks and overlapping the edges of the side walls thereof and a cross-bar integral. and fiush with the side and tread surfaces of said cushion pads and connecting the latter through the open sides of said heel-calks, a hollow toe-call; formed with outer, inner and side walls, a cushion pad filling said toe-calk and overlapping the .edges of the walls thereof flush with the outer sides of said walls, and intermediate transversely beveled sharp-edged calks springing fromthe inner'edg'e of said baseplate and connecting and continuous with the inner walls of said toe and heel-calks.

i. A cushion-tread horseshoe comprising an ovate apertured base-plate having curved widened heel portions spaced apart; a pair ofhollow heel calks each having an inner end wall, an outer side wall extending from said end wall along the outer edge of the base to approximately the end thereof, and an inner side wall extending from said end wall along the inneredge of the base ap-' proximately half the length of the outer wall, a hollow toe calk and tapered intermediate calks extending'along the inner edge of the base from the inner wall of the toe call: tothe inner walls of the heel calks, and toe and heel cushions, the latter consisting of cushion pads filling said heel calks and keyed to the base and an integral cross bar flush with the tread of said cushion pads and filling the gap between the ends of the base.
